Introduction

Indigenous knowledge of ethno-veterinary medicine uses for curing different ailments of animal and birds is an old practice since time immemorial. Ethno-veterinary system is based on folklore, beliefs, knowledge wisdom and their skill of handling the medicinal plant species acquired by the local livestock holders. Ethno-veterinary practices are sometimes experimental methods developed by the local herdsmen. Rural dwellers depend on livestock for livelihood, economic security, food and therefore it is an utmost necessity to take help of cheap, easily accessed, safe local resources which are tested for long time on the animals. Ethno-veterinary medicine and its importance has been identified by ethnic groups long ago. It is used effectively for primary health care treatment of the animals for health and productivity which provide an alternative to expensive drugs available in the market. It is also reported that though classical system of treating ailment is familiar to all over the country, yet these systems are known to few individual . Ethno-veterinary serves as alternative of conventional medicines for preventing ailments and use of medicinal plant in ethno-veterinary is one of the integral parts which have broad spectrum and seen to be used in treating many ailments .

Mention may be done of veterinary practices prevailing from the Vedic period where Hindu Vedas, Puranas and ancient books has mentioned the vast treasure of plant species used in the alleviating animal health problems .

India is rich in both floral and faunal diversity and has a huge wealth of livestock. India is one of the world’s 12 mega diversity country and account for 8% of global plant resources. It is reported that 35,000 species of plant are known to have healing properties. 75% of world population depends on medicinal plants . According to a report of WHO, 80% of people in developing countries reckon on traditional knowledge for curing various ailments of both human and animals .

Being a developing country, 80% of poor population depends on agriculture. Animal rearing is gaining importance and every rural household is seen to be a part of it. Livestock has contributed to the development of socio-economic development of rural household and to the industrial sector with its by-products.70% of rural household in India owns livestock are poor landless household who prefer animal rearing due to low initial investment. On the other hand, livestock provides a variety of food (meat, milk, eggs etc) and non-food products (wool, fur, fibres, skins, organic manures etc) and contributes nearly 25%to the gross value of agricultural output. Import and export of livestock has also got important share on economic upliftment of the country. Not only plants have got medicinal property, but also animal equally have ethno-veterinary medicinal properties, however this use have been neglected in comparison to medicinal plant research. It is indispensable to identify and document the medicinal plant used by the farmers with the aim on maintaining the cultural practice.

Methodology

Study area

Dhemaji district is one of the remote rural districts of the state which is situated on the north bank of river Brahmaputra. Geographically situated between 94°12’ 18’’ E and 95°41’32” E longitude and 27°05’27’’ N and 27°57’16’’N latitude and covers a distance of 3237 sq.km. Many ethnic groups of people inhabit the district- Ahoms, Kalitas, Tiwa, Boro, Misings, Kacharis, Hajong, Deoris etc. All are knowledgeable about the use of traditional herbal medicines to treat their livestock health related. Agriculture is the main economy of the people, but side by side animal rearing is also one of the occupations of the district and plays a vital role in socio-economic development of the rural areas. Frequent flood related problems stand as a barrier to the economic development of the district. As per the 19th livestock census 2012 there were total cattle population-4,69,219, Buffaloes-21,635, Goats-143,154, Pigs-132,427, Fowl-604,542 and Duck-224774 nos.

Data collection

A field survey was conducted randomly in ten villages (Sripani ahom gaon, Morol gaon, khalihamari gaon, kashoiting gaon, khajua, Ramyapur, Amguri, Jiadhol, Naharani gaon, Naruathan) of Dhemaji district by performing semi-structured interviews, group discussion and free conversation was conducted with the local animal rearers for gathering ethno-veterinary knowledges. During the interview period well, knowledgeable people were chosen, and photographs of the animal diseases and plant species were shown to them so that no confusion remains. Mostly the elders were observed to have the knowledge of the traditional knowledge irrespective of the gender. It was observed during the study, the animal holders were low income, uneducated simple living people. Simple questions were asked regarding the animal they rear, health related problems of the animals, healing practice with the help of plant species, mode of preparation of the medicinal doses. Information about the part of the plant used as medicine, vernacular name of the species, and seasonal availability of the particular species were recorded. They have also informed the traditional healing practice was acquired either by seeing or verbally from their forefathers or learned by experiments. They mostly prefer home remedies rather than going to the veterinary hospitals because of the distance related issues. Most of the village people have the same knowledge of ethno-veterinary as the remedies keep on circulating between them.

Present study is an attempt to document the medicinally important plant used to treat animal health related problems. Plant specimen were identified by using.

Results

In the present study a total of 36 plant species were identified for the treatment of 22 common ailments of livestock belonging to 34 genus and 31 families. Common ailments in livestock and poultry includes fever, dysentery, bloating, diarrhoea, galactogogue, anthrax, urine problem. shows that the plant species found in the study,3 belongs to Solanaceae, 2 belongs to Lamiaceae, Rutaceae, Clusiaceae and Poaceae and 1 plant species belongs to Acanthaceae, Amaryllidaceae, Alliaceae, Apiaceae, Asphodelaceae, Asparagaceae, Asteraceae, Araceae, Brassicaceae, Caricaceae, Caryophyllaceae, Combretaceae, Convolvulaceae, Crassulaceae, Dilleniaceae, Fabaceae, Malvaceae, meliaceae ,Moraceae, Musaceae, Oxalidaceae,Piperaceae, Rosaceae,Thelypteridaceae,Vitaceae, Zingiberaceae according to the. The use of leaves (48%) is mostly found in the treatment of animals and poultry health problems, followed by fruits of the plant species (21%), seeds (9%) rhizomes (6%), bulb, roots, stem (4%), barks and peel (2%) respectively. Most of the medicines are administered orally and topically to the animals. shows the health problems of the livestock, local and scientific name of the medicinal plants used for the treatment, parts of the plant used, family to which a plant species belongs and mode of preparation of the medicines to be administered. Oral administration (72%) of the medicines prepared traditionally to treat various health issues of the animal and poultry is higher than topical administration (28%) .

Discussion

Medicinal remedies are used solely or sometimes combine with other species to prepare the medicinal dose. In the present study, the herbal medicines are seen to be prepared by combining more than one plant species. Seeds of Brassica juncea crushed along with Curcuma longa powder and Zingiber officinale paste and the juice is given orally to treat fever in cow and goat. An equal number of leaves of Leucas aspera, tulsi, pepper, black cumin is crushed and fed orally for ruminal tympany in cow and goat. Bark of the Terminalia arujuna tree is crushed and a fine paste Allium sativum is prepared for treating bone fracture. Ripe Piper betel leaves and few seed of Cuminum cyminum is crushed together and fed treat dysentery in cow and goat. Leaves of Centella asiatica are crushed with piper nigrum and given to eat to cure fever in pig but in case of hen and duck only the leaves are crushed and given to eat. Leaves of Ipomoea aquatic is mixed with Amaranthus spinosus, ginger, seasame and fed to treat galactogogue in cow, goat and buffalo also the seed of the same plant species is used in treating anthrax in pig, cow, goat, buffaloes.

During the survey, observations are made of the use of one plant species for treating different ailments. Leaves of Leucas aspera is used to treat ruminal tympany in cow and goat as well treating diarrhoea in poultry (hen and duck). Fruit of Citrus aurantifolia is used for dysentery in hen and pigeon and even cataract in cow, goat, buffalo and pig. Rhizome of Curcuma longa is seen to be used for the eye problem in hen and pigeon and even to cure the throat infection in cow, goat, buffalo and pig. Allium sativum bulb is seen to be used in ruminal tympany in cow and goat as well as in treating worms on wounds. Lasia spinosa rhizome is used to cure dysentery in pig and the stem of the same plant species is used to treat worm problem in pig. The leaves of Azadirachta indica are given to cow, goat, pig, buffalo to remove weakness and the juices extracted from the same plant species are applied on the affected area to treat fungus on cow and goat. From the study it is found that the leaves of Nicotiana tabacum is used to treat fungus and tick problem in cow and goat.

Traditional healers use the plants parts in the form of paste, decoction, juices, and powdered form for the ailments. The study documented the use of weaver ant (Oecophylla smaragdina) along with the fruit of Capsicum annuum for treating fever in Hen and pigeon. Throat infection of cow, goat, buffalo, pig is cured when rhizome of Curcuma longa is mixed with honey. The study also documents the use of fermented Oryza sativa mixed with dried fishes to treat diarrhoea in hen and duck. Therefore, use of insects and fish along with the plant species is well observed.

Traditional healing practices by the ethnic community is prevalent in the rural low marginal income animal rearers. Use of leaves, roots, rhizomes, bulb, fruits, seeds, stem, bark of the plant are seen to be used in ethno-veterinary practices and is documented by many authors in their surveys. Use of plant in treating ailments in human is well explored but few studies have been reported regarding animals. A survey in Udaipur district has reported 62 plant species for the treatment of 30 diseases in domestic animals.

It is mentioned to use Allium sativum for weakness, foot and mouth disease, Aloe vera for burn and inflammation, Azadirachta indica for leucorrhoea, Triticum aestivum for galactogogue but same plant species are not found to cure the same ailment in the present study. Another study from western Morang district of Nepal has recorded the use of 37 plant species for 21 ailments. Modes of preparation, application of the medicine and ailments are an essential component in ethno-veterinary most common disease and the plant uses reported are Dalbergia sisso for diarrhoea, Leucas aspera for flatulence, Asperagus racemosus for milk production, Allium sativum for tail cut, Brassica napus for chronic cough. Most frequently used parts are seeds and fruits. Use of medicinal plants for the same ailments differs from place to place due to difference in knowledge, way of observing the ailments symptoms.

A report from the Cholistan desert has documented 77 ethnoveterinary practices comprising 49 plant uses and 25 dairy-based products, chemicals. A total of 18 plant species were documented belonging to 14 families for the treatment of parasitic diseases in the livestock. Livestock are the main source of livelihood and treasure for the remote dwellers. Ethno-veterinary curative measures prevailing among the tribes of Eastern Ghats has been reported with the use of 35 species for treating anthrax, ephemeral, fever, trypanosomiasis. Besides the use of herbs, shrubs, plant, use of Hedyotis corymbosa (Linn.), a weed has got medicinal property in curing animal health problem. Traditional healing practices is well documented with the use of 74 plant species for the treatment of rheumatism, fever, bloat, mouth disease, constipation, expulsion of placenta after birth etc by the local communities of the Porbandar district, who are well knowledgeable in handling the medicinal plant. A study conducted in Zimbabwe has documented use of 12 medicinal plant for major poultry health problem in respiration, external body parasite etc.

A use of 34 species of angiosperm belonging to 30 genera for treating various health related problem by the villagers of Puthalam, Cape Comorin of Tamil Nadu state. The use of leaves is reported to be used more than the other parts of the plant. Traditional knowledge of ethno-veterinary use is depended on availability of certain plant species in the particular season, favourable climatic condition of the area. Traditional healers classify the diseases on observing the signs and symptoms and accordingly treatment is provided. Cestodes and Nematodes are reported to be the dreadful parasites of ruminant livestock of developing countries. Ethno-veterinary practices are also reported in deworming preparation. The plant extracts are constituent of anti-microbial property which helps in improving the animal disease resisting capacity. The present study emphasises on the identification of the plant based medicinal treatments used in curing the health-related problems of livestock and will help in further phytochemical study on crude drugs.

Conclusion

Ethno-veterinary practice is unique from villages to villages which are passed on orally from one individual to another and remain confined to them. Treating animal health related problem with traditional knowledge is due to inhibition of rural people in remote areas and their difficulties in reaching far-flung veterinary centres, making them unable to avail the modern medicinal treatment. They are obliged to depend on low cost, easily handle medicinal plant available in nearby dwelling areas. This study would keep the rich knowledge of treating ailments with the help of plants alive and further open a way for recognising the proper medicinal plant. It will also prevent destruction of the plant species due to anthropogenic activities and identify the traditional healers who treasure the use of ethno -veterinary practices among themselves. Conservation of plant species may give a chance for farming of medicinal plant and to be economically stable by selling the cultivated floral species, thus benefitting both the livestock and poultry holders and the plant cultivator. The present study also gives an opportunity for scientific studies on the chemical compound present in the medicinal plant and even may give a chance for alternative pharmaceutical drug production.
